From a134f85c131ffd56720e38af2967ec6265480757 Mon Sep 17 00:00:00 2001 From: Balazs Scheidler Date: Thu, 20 Nov 2008 01:07:24 -0800 Subject: [PATCH] TPROXY: fill struct flowi->flags in udp_sendmsg() udp_sendmsg() didn't fill struct flowi->flags, which means that the route lookup would fail for non-local IPs even if the IP_TRANSPARENT sockopt was set. This prevents sendto() to work properly for UDP sockets, whereas bind(foreign-ip) + connect() + send() worked fine. Signed-off-by: Balazs Scheidler Signed-off-by: David S.
